The focus of this research was to formulate optimization model 16-bar trussesalong with stress, stability and deflection constraints. derivative free methods were used for theoptimization engineering design problems. These basically designed forunconstrained In formulated truss problems the constraints werehandled by using exterior penalty functions. results obtainedby MATLAB which demonstrated...

One of the subjects in solar water heater design is considering distribution of hot water consumption during the day. For example, each of the household, commercial, office, school, and industrial consumptions have a particular distribution of hot water consumption named pattern in this article. In solar computation principles, the effect of longitude, latitude, and altitude on collector angle ...

This paper presents an energy management strategy to supply residential load by hybrid fuel cell power plant (FCPP). Economical fuel cell (FC) model includes thermal load, local electrical load, operational cost, startup cost and different tariffs on electricity during the day hour is discussed.  Several Strategies have been presented for supplying residential load (electrical and thermal loads...

due to limitation of available water and soil resources in iran, the challenge of optimizing the utilization of these resources has become more significant. one of the solutions to the economic, planning and optimization of water use and achieve the optimum level of water use is associated with improved farming activities and this is the most important agricultural research needs. the study of ...

ABSTRACT- This study aims to model optimal cultivation pattern based on the maximization of importing virtual water and social net income of major crops in Marvdasht, Iran. For this purpose, a linear programming model was developed considering constraints of virtual water and land limitations followed by other models to include employment restrictions. Based on the findings, wheat and tomato we...

In this paper, we consider the pattern matching problem in DNA and RNA sequences where either the pattern or the text can be degenerate i.e. contain sets of characters. We present an asymptotically faster algorithm for the above problem that works in O(n logm) time, where n and m is the length of the text and the pattern respectively. We also suggest an efficient implementation of our algorithm...

We draw on an ecological metaphor to analyze terror defense by governments and individuals. Governments can combat terror in part by targeting what we call the “stock of terror capacity” accumulated by a terrorist organization. The optimal control of terror stocks relies on both periodic cleanup and ongoing abatement, a lesson derived from the optimal control of other stocks of public bads, suc...

We introduce a general methodology for parameter identification in reaction-diffusion systems that display pattern formation via the mechanism of diffusion-driven instability. A Modified Discrete Optimal Control Algorithm is illustrated with the Schnakenberg and Gierer-Meinhardt reaction-diffusion systems using PDE constrained optimization techniques. A quadratic cost functional that measures t...

This paper extends Turing analysis to standard recursive optimal control frameworks in economics and applies it to dynamic bioeconomic problems where the interaction of coupled economic and ecological dynamics under optimal control over space creates (or destroys) spatial heterogeneity. We show how our approach reduces the analysis to a tractable extension of linearization methods applied to th...
